VALVE.

SPECIFICATION forming part of Letters Patent No. 510,883, dated December19, 1893. Application filed September 11,1893. Serial No. 485,246. (Nomodel.)

To @ZZ whom it may concern:

Be it known that we, JOHN J. BOYNE and WILLIAM CALDWELL, citizens of theUnited States, residing at the city of Budalo, in the county of Erie andState of New York, have invented a new and useful Improvement in yalves,of which thefollowing is a specificaion.

This invention relates to that class of valves rately guide the valvesto their seats.

In the accompanying drawingss-Figure 1 1s a sectional elevation of ourimproved valve. Fig. 2 is a horizontal section thereof, the plane o fsection being through the rock shaft. Fig. 3 1s a similar section online 3 3, Fig. 1.

Like letters of reference refer to like parts in the several figures.

A represents the cylindrical casing of the valve which is preferablyprovided at its lower end with ears c for securing it to the iloor orother support.

a is the inlet branch of the valve which is arranged on one sidethereof, near its lower end, and to which the Water supply pipe isconnected. a2 is its outlet branch which is arranged at the upper end ofthe casing and to which is connected the pipe which leads to the bowl ofthe closet or the usual elevated supply reservoir; and as is the branchthereof with which the usual drain or waste pipe is connected and whichis located opposite the inlet branch c. The water supply pipe, the pipeleading to the bowl or reservoir and the waste pipe are connected withthe corresponding branches of the valve by the usual unions or couplingsa4. The inlet and waste pipe branches or connections of the valve areconstructed of uniform size or diameter as shown, so that, if desired,the position of the valve may be reversed and the inlet branch be usedas the waste branch and the latter as the inlet brauch.

B is an upright or longitudinal diaphragm arranged centrally in thelower portion of the valve casing and dividing the latter into twoindependent valve chambers O C of substantially semi-circular crosssection, as shown in Fig. 3. The inlet branch 'a' communicates with oneof these valve chambers, while the waste branch a3 connects with theother chamber.

D is a horizontal diaphragm which forms the top of the valve'chamber andseparates the same from: the upper portion or chamber of the valvecasing. This diaphragm is formed with openings or passages d, wherebythe valve chambers communicate with the upper chamber of the valvecasing.

E is a cutoff valve arranged in the inlet chamber C and controlling thepassage of the water from the supply branch into the upper chamber ofthe valve casing, and E is a similar valve arranged in the waste chamberO and controlling the dow of the Water from the upper chamber of thevalve casing tothe waste branch. Each of these valves consists of a diskof leather or similar material which is attached to the lower end of avalve stem e2 passing through the passage d in the top of thev valvechamber. These valves are adapted to close against seats arranged at thelower ends of the passages d. To the under side of each valve isattached a guide f consisting of a semi-circular plate which is fittedclosely in the correspondingly shaped valve chamber. This plateaccurately guides the valve in its movements and causes the same to bearsquarely against its seat. The upper ends of the valve stems e2 areattached to rock arms g g secured to diametrically opposite sides of arock shaft G arranged transversely in the upper portion of the valvecasing, so that upon rocking said shaft one of the valves is closed andthe other opened. The inner end of this rock shaft is formed with ajournal g which turns in a bearing g2 formed in the adjacent inner wallof the valve casingLwhile the outer portion of the shaft extends througha cylindrical stuiing box h arranged. in the opposite Wall of thecasing. This stuffing box is formed in its in IOC ner end with acontracted seat h', which receives a collar or fiange g3 formed on theadjacent portion of the rock shaft.

a is a retaining ring or washer surroundlng the rock shaft on the outerside of its collar and bearing against the annular shoulder or offset z"formed at the outer end of the seat h.

.7 is a packing ring of rubber or other suitable material whichsurrounds the rock shaft between such retaining ring and a gland kfitted in the outer portion of the stuffing box. This gland istightened, for compressing the packing ring, by means of a screw capZwhich engages with an external screw thread formed on the stufing boxand which is formed with a central opening for the passage of arockshaft. The latter is held against lengthwise movement by its collarwhich is confined between the bottom of the seat h and the retainingring, but as the latter bears against the shoulder t', it relieves thecollar from the pressure of the packing and avoids clamping of the sameagainst the bottom of the seat h. The shaft, while capable of beingtightly packed, is thus free to operate with a minimum amount offriction. By supporting the inner end of the rock shaft in a bearingwithin the casing, cramping or binding of the shaft is effectuallyprevented.

M is the actuating arm or lever which is attached to the projectingouter end of the rock shaft for operating the same, and N is the Weightarranged upon the long arm thereof, which tends to tu rn the shaft inthe proper dlrection to close the supply valve and open the waste valve.

O is the rod which is connected to the short arm of said actuatingleverand which may be attached to the vertically movable closet seat orterminate in proximity thereto, in a well known manner, so that when theseat is occupied, its depression causes the rod to swing the lever inthe proper direction to open the supply valve and close the Waste valve,so as to flush the closet. If desired, the actuating lever maybeoperated by hand by means of a chain attached to one of the perforatedears n of the Weight N.

The actuating lever M is provided with a square or flat sid ed openingwhich receives the correspondingly-shaped outer end of the rock shaft,and the lever is removably attached to the latter by a pin or othersuitable means, so that the same may be reversed on the shaft, when theposition of the valve is reversed for bringing the weight N on theopposite side of the valve casing. By so constructing the two valves,their valve chambers and the inlet and waste branches of the valvecasing, that one set of such parts is the duplicate of the other set andmaking the actuating lever reversible, either side of the valve can beused as the inlet side and the other as the waste side, thus enablingthe pipe connections to the valve to be made in the most convenientmanner and without the use of extra pipes, which is necessary with anon-reversible valve, in case the arrangement of the pipes is such as toprevent a direct connection thereof to the supply and waste branches ofthe valve. The valve is placed below the frost line in a well knownmanner.

When the valve is used in connection with a water closet and the closetseat is unoccupied, the supply valve is closed and the waste pipe isopen, as shown in Fig. 1, thus permitting the water in the water pipeconnected with the upper branch of the valve casing to escape throughthe valve into the waste pipe, whence it may be discharged into the trapof the closet or into the sewer. When the seat is occupied, the Wastevalve is closed and the supply valve opened, allowing the Water to passthrough the valve to the bowl or to the supply reservoir, when such areservoir is used.

Although our improved valve is especially desirable as a water closetvalve, it is equally useful in connection with wash stands, bath tubs orother Water fixtures, in which the pipes are liable to become frozen.

We claim as our inventionl. In a reversible valve, the combination withthe casing provided at its top with an outlet and on opposite sides ofits lower portion with inlet and waste branches or connections, of alongitudinal diaphragm dividing the lower portion of the casing into twosimilar valve chambers which communicate respectively with the inlet andwaste branches, a transverse diaphragm forming `the top of said valvechambers and having passages, reciprocating valves arranged in saidchambers and adapted to close said passages, a transverse rock shaftarranged in the casing above its transverse diaphragm and having rockarms on opposite sides, and stems connecting the valves with said rockarms and extending through the passages of the transverse diaphragm,substantially as set forth.

2. In a valve, the combination with the cylindrical casing provided onopposite sides with inlet and waste branches, of a longitudinaldiaphragm arranged centrallyin the lower portion of the casing anddividing the same into two valve chambers of semi-circular crosssection, valves arranged in said chambers and having semicircular guideplates fitted closely in said valve chambers, a transverse rock shaftarranged in the `upper portion of the casing and having rock arms onopposite sides, and stems connecting said valves with said rock arms,substantially as set forth.

Witness our hands this 18th day of August, 1893.
